Title: Ground traveling route supporting device for aircraft
Inventor: KAI HAJIME
IPC: B64F1/36
Filed: 1989-06-29
Abstract: PURPOSE:To secure safety for the travel of an aircraft in an airport by executing the guidance of a new ground traveling route as information to an air-traffic control staff when the aircraft gets out of the ground traveling route instructed by the air-traffic control staff. CONSTITUTION:When a signal showing that the aircraft gets out of the ground traveling route is inputted from a traveling route discriminating device 21 to a system controller 5, an alarm controller 24 and a route data calculator 32 are activated. An alarm display panel 23 is turned-on by the controller 24 and the air-traffic control staff can confirm that the aircraft gets out of the ground traveling route. On the other hand, when route data are inputted from the calculator 32 to a traveling route display device 33, the route is displayed on a monitor and thus, the guidance of the new ground traveling route can be executed to the air-traffic control staff as the information. When the route is displayed by the device 33, the air-traffic control staff instructs the displayed route to a pilot.

Title: Magnetic head
Inventor: HAMANA JUNJI
IPC: G11B5/187
Filed: 1989-06-30
Abstract: PURPOSE:To prevent dust pickup and to stabilize electromagnetic conversion characteristics by providing hollow grooves to prevent the sliding contact of a perpendicular part with a recording medium on a recording medium sliding surface and forming a parallel part by using a resin having hollow holes on the sliding surface. CONSTITUTION:A hollow granular material 5 having 1 to 200mum bore is packed into an epoxy resin 4 and is used as a resin for fixing. After this resin is cast into a shielding case 2 and is cured, the sliding surface side of the magnetic head is ground to form the fine hollow holes on the sliding surface. The growth of the dust sticking to the part parallel with the medium sliding direction is, therefore, stopped by the hollow holes. Further, the fixing material in the part perpendicular to the sliding direction is removed by grinding to from the hollow grooves 6 perpendicular to the sliding direction. The resin for fixing existing at the end of magnetic cores 1a, 1b parallel with a gap G does not, therefore, come into sliding contact with a magnetic tape 3. The pickup of the dust is obviated in this way in spite of the long-time sliding and the deterioration of electromagnetic conversion characteristics and the generation of stick-slip are prevented.

Abstract: PURPOSE: To provide a process for producing a high-precision micromechanical element.  
     CONSTITUTION: A recessed surface forming the edge of an undercut is manufactured by growing a projecting buffer material into the wall part of the static structure extending from a flat surface within this wall part. This buffer material forms a projection and recess relation with the wall part. In succession, the buffer material is removed from the wall part in such a manner that the recessed undercut surface of the wall part is maintained. In succession, the static structure and the flat surface are further processed by coating with a sacrificial layer and a structural layer. This structural layer is patterned and formed to constitute a movable structure held on the surface of the static structure by the edge of the undercut curved like a slot within a slider 30.
